If you deduplicate non-root-visible types, the resulting type should still be non-root-visible! We were promoting all such types to root-visible, and re-demoting them only if their names collided (which might happen on cu-mapped links if multiple compilation units with conflicting types are fused into one child dict). This "worked" before now, in that linking at least didn't fail (if you don't mind having your non-root flag value destroyed if you're adding non-root-visible types), but now that conflicting enumerators cause their containing enums to become conflicted (enums which might have *different names*), this caused the linker to crash when it hit two enumerators with conflicting values. Not testable in ld because cu-mapped links are not exposed to ld, but can be tested via direct creation of libraries and calls to ctf_link directly. (This also tests the ctf_dump non-root type printout, which before now was untested.) libctf/ * ctf-dedup.c (ctf_dedup_emit_type): Non-root-visible input types should be emitted as non-root-visible output types. * testsuite/libctf-writable/ctf-nonroot-linking.c: New test. * testsuite/libctf-writable/ctf-nonroot-linking.lk: New test.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
